Be it known ahnt "il, JAMES G. Hnfisin'r, o citizen oi' @he Unieo".

The magneto is noi iilusti'ated, as is a Weiiknown type of device ioi piodncing eieo'ii'io energy. @ne fiole oi said iniigneio is gionnd ed upon one motor, Wliiie 'one other pole is Connected through insulaiecl Wiies and oondni'te, W i the insulated eleotiodes-oi lie igni'tei plugs, 'Refoi'i'ing to the drawings-Tile numerals l denote plugs adapted to oe inserted in tlie cylinder heads of of ges engine and oeai the several parte of the operating meononiein of the make ind break device. They are bod-- ily removable und may be readily inserted in the cylinder heads, They of oouise may be used on n, motor having any number of cylinders and are so interconnected that the conz'ol b ineolimiisin iioi Varying the instent of igniiion in one oyi oder, will simni taneonsiy Very in iile proportion, the timing oi the instant of ignition in the seveiei com iled mechanisme. The plugs i, have mein inody port- 2 oi' cjyiindiiieui form, surmounted by a oop oi' flange The body Dort 2 is of considerable depgli and extends enough the head and jacket of the cylinder in such nio-nner that lthe make and break. for disrupting -tlie Circuit extends into the combustion chamber of' the ,fiindei'.

This insulated e /trofle 4 projects through the plug and lies oposition to be engaged oy a niombie electrode 7.

lated pl will be noted that the movement ol` the trigger or iinger 1u, will move the movable electrode against the insulated electrode through the medium of thespring 11, which is of course of sulhcient tension to overcome the ring 13. This spring arrangehe necessary compensation for h and insures a posihe movable electrode pull of' the sp ment allows t high" and low spar tive contact between t and insulated electrode at all speeds of the 'l`he spring 13, on the other hand, tion of the movable electrode. etrode at a uniform spec no matter what the speed of the engine, thus maintaining the drawing of a spark or are of uniform quality. lt will therefore be seen that no matter what the instant ol ignition, the speed ol" separation of. the'contacting points will be constant, and' will therefore produce a uniform spari; irrespective of the speed ol the engine, 1 i

The trigger 1U and its movable electrode 7 are moved into contactnig position with the plug or insulated electrode 4 by atrip lever l-l. 'l`his leve 15 eccentrically ar insures a separa and insulated ele ranged upon the eccentric dish lo, which is secured. to the upper end of a ,shaft 17, the lower end oi which terminates in a/geur 1B. This gear 1S meshes with gear ugs or insulated electrodes 4, and it -the'spring connection 11 and movable electro r is mounted upon a bearing 19 upon the'shaft 2U, which oi course is directly geared to the engine shaft. The shaft :ZU is the time shaft which bears the cams for operating the vinlet valves oi the engine cylinders. From the above it will be seen that the trip lever 14 is positively driven from the engine shaft and will be rotated at a speed varying with the speed ofthe engine. 'lhe eccentric dislis 16 are made adjustable upon theirshafts in order that the trip levers 14 may be set to the proper initial position providing a uniform movement fort-he severa cylinders.

Mounted upon the plug 1 is a timing eccentric 21 having an extended lever 22 provided in its outer and under side with a roll 325 which irojeets into a cam groove shaped in tile form of a thread. or cam groove is out in a eylind is secured to and rotates with a s ably suliported with reference to the engine cylindersand igniter plugs. shaft 26 bears a pinion 27 which meshes with a segmental gear 2B, secured to the upper end ol a lshaft 2S). The lower end of this shaft, through a lever 30 and 4suitable connections (not-shown), may he rotated by the operator whenever it is desirable to change the instant ol' ignition for securing variations of speed of the engine.

Obviously the movement of the shaft 'Z9 will rotate the screw eamiblock 25 andv swing the timing eccentric 2l throughthe medium of its lever 22 and roll 23. As shown in the drawing, the timing lever Z2 is shown in advanced position, and in this position the trip lever 14 will engagev and remain in engagement with the trigger 10 for the shortest time possible `with the arrangement, of .parts illustrated. vo retard the instantof ignition, the cam block 25 isv rotated, throwing the timing lever 2 2 to a greater or less extent and permitting the tripleverlev to assumea lower position upon the timing eccentric "21; This vof course v permits a longer engagement' of the end 32 of the lever'14 and the trigger 10. This results in holding the movable electrode 7 against vits insulated lelectrode a longer S5 period of time, and of course this difference' of time in contac t of the parts 1s permitted by between the trigger de shaft 8. v v It will be noted from theabove /descri ition, that the speed with which the movable electrode 7 is moved into contact with the insulated electrode or plui, depends upon the speed of the engine, vut whenever the* lever 14 triv s or drops the trigger 10, the 95 s 'iring 13 wi l react, always moving the mov v i a le electrode 7 and disrupting the circuitat r' a constant speed virrespective `of the speed of the engine.

' The current'iroxn one pole of the magneto 100 or source oi' electrical energy is preferably carried to the bus bar 6 through an insulated wire 33, and in practice it is found 4con? I veulent to arrange this bus'bar over the cyl 1 inder heads. The flexible conductors 5 4105 which connect the bus bar. with the plugs or insulated electrodes 4 are provided with sleeves 34 which fit tightly over 'the upper ends of the plugs 4, and may be readily removed to break the circuit for cylinder. But one plug has been described A herein, as the operating parts for itfare idenof course it is understood that any f number of plugs may be used fora eorresponding number of cylinders, the several plugs being interconnected as 'illustrated in the couplet shown in the drawing.

Obviously the details might he varied to a without departing from the spirit or intent of the invention, and various forms of positive connection might be utilized in lieu of thespeeiie forms shown herein.
